Development of visuals card as educational media to improve student’s achievement on the science concept of “Human musculoskeletal system” for 5th grade of elementary school at Depok City

This research aimed to develop visual-based science learning media on human musculoskeletal system material as an effort to improve student’s achievement and understanding in mastering the material. This media was arranged in a card product called VISUALS Card. This product could be an alternative learning media for educators in the use of instructional media. The researchers applied research and development (R & D) method and used Dick and Carey’s development model consisting of 10 development steps. The feasibility test of the media was conducted by involving material experts, linguists, media experts, and students. The research involved material experts as much as 88.33%, linguists as much as 86.67%, and media experts as much as 90% in which it stated that the media was worthy of use. The effectiveness of the feasibility was conducted on individual tests, small scale test, and large scale test. The effectiveness test was conducted in 3 elementary schools including SDN Sukatani 4, MI Nurul Falah, and SDIT Amal Mulia. The results of pre-test and post-test had increased so it could be concluded that the VISUALS Card media could improve the achievement and understanding of the science concept on human musculoskeletal system material. The advantage of the VISUALS Card media was that it could be used for individuals, in pairs, in groups, and for the learning in a big class
